APPARATUS FOR PURIFYING AIR.

Specification of Letters Patent.

Application filed May 15, 1911.

Patented Aug. 22, 1911.

Serial No. 627,242.

To all whom it may concern:

Be it known that I, FRIEDRICH Gnons JANICH, subject of Germany, residingat Rheydt, near Dusseldorf, Grermany have invented certain new anduseful Improvements in Apparatus for Purifying Air, of which thefollowing is a specification.

This invention relates to an apparatus for the production anddistribution of ozone in the air of a room or the like and its intimatemixing with this air with the object of purifying the latter.

This apparatus consists broadly of a fan combined with an ozonizer insuch a manner that the air displaced by the fan draws the ozone from thedischarge conduit of the ozonizer which produces an intimate mixing ofthe ozone and air. The fan is placed above the ozonizer and thedischarge conduit of the latter opens in front of the blades of the fanbehind a funnel-shaped screen with closed bottom arranged coaxially withthe fan at a small distance therefrom in such a manner that the eddiesof the air produced by the rotation of the blades of the fan strikeagainst the closed bottom and the outer walls of the funnel thusproducing a partial vacuum in the latter and consequently a suction ofozone out of the discharge conduit of the ozonizer.

In order to increase the suction of the ozone and to render itsdistribution in the air more uniform a second screen of the same shapeas the first is fitted into the latter but is separated from every partthereof by a small interval in such a manner that the discharge conduitof the ozonizer opens between the closed bottoms of the two screens andthe ozone is drawn between the inner walls of the first screen and theouter walls of the second screen and escapes between their outer edgesdirectly into the current of air produced by the fan.

An embodiment of the invention is illus trated by way of example in theaccompanying drawing in which:

Figure 1 is a side elevation of the apparatus partly in section and Fig.2 is a front elevation of the distributing screens and of the dischargeconduit of the ozonizer.

In this embodiment of the invention the fan a is mounted directly uponthe ozonizer Z) which serves as a bracket. The ozonizer consists of asmall transformer the low tension coil of which is connected with theterminals 0 of the electric motor (Z of the fan while its high tensioncoil is connected with glass plates covered with tin or an equivalentsubstance.

6 is the discharge conduit for the ozone which ascends in front of theblades of the fan; at its upper end the screens f and g are mountedco-aXially with the said blades and connected one with the other andwith the conduit 6 by a short tube It with orifices z.

IVhen the fan is operated the displacement of the air produces suctionin the direct-ion indicated by the arrow in Fig. 1 and the ozone drawnfrom the conduit 6 is uniformly distributed throughout the air inproportions that may be caused to vary at will by modifying the speed ofthe fan or the production of ozone.

That I claim and desire to secure by Letters Patent of the United Statesis 1. An apparatus for the distribution of ozone in the air comprisingin combination a fan, an ozonizer with discharge conduit opening infront of the blades of this fan and a funnel-shaped screen with closedbottom arranged between the said blades and the discharge conduit.

2. An apparatus for the distribution of ozone in the air comprising incombination a fan, an ozonizer with discharge conduit opening in frontof the blades of this fan and a screen formed by two funnels with closedbottoms fitted one within the other and separated from each other by aninterval into which the discharge conduit of the ozonizer opens.

3. An apparatus for the distribution of ozone in the air comprising incombination a fan, an ozonizer the discharge conduit of which opens infront of the blades of this fan, a funnel-shaped screen with closedbottom arranged between the said blades and the discharge conduit and asecond funnel shaped screen with closed bottom fitted into the first andseparated therefrom by a space into which the said discharge conduitopens.

4. An apparatus for the distribution of ozone in the air comprising incombination an electric fan, a bracket upon which this fan rests, anozonizer housed in this bracket, In testimony whereof aifix my signaitsdischarge conduit opening in front of the ture in presence of tWowltnesses.
